Fingering with precum

On 5/8 i had seen my bf and we had no PIV but we did oral and I'm afraid that when he touched his penis it may have had precum. About 15 mins later he fingered me and it was deep. I'm afraid I could be pregnant. Usually my cycles are all different but I was supposed to start my period on 5/27 and it is now 5/30 and no period.

I'd only started to think about this after he had left and I've been overthinking it for weeks and I'm afraid of taking a PT because I'm afraid it may be positive. Pls help or any advice to induce my period?

Edit: i've also been feeling slight pains in my chest and my right abdominal, but they go away almost immediately after

Update: i got my period and i am not pregnant !!
